How to solve the dies bounce of the hose crimping machine during processing?

How to solve the mold bounce of the hose crimping machine during processing? The hose crimping machine is a hydraulic automatic hose end processing machine controlled by the integrated control touch display screen to expand and crimp the end of the hose under normal conditions. The replacement of the mold can expand, shrink, bulge, and upset the pipe. The pipe ends such as ribs are processed and formed, and the user can freely decide to use manual, inching or automatic processing. The machine tool consists of oil tank, bed, slider, main cylinder, mold core rod (optional), limit cylinder, and compression cylinder. , Clamping mold, axial positioning cylinder, axial positioning angle iron and other main parts. Structure: Weld a site with channel steel, and the power end is equipped with a motor, a reducer, and a chuck (for pipe clamping, it can be replaced by a lathe chuck). A support base (openable) is installed at the other end, and a heating ring is fixed on the outer end of the support base (8-10 nozzles, welded to a copper pipe ring by gas welding). Outside Z is a movable support, on which an alloy mold is installed. How to use: Fix the tube on the hose crimping machine and turn on the heater (ring). After the temperature is reached, the alloy mold is pushed, and the shape of the tube head meets the requirements. The whole process takes about 15 minutes. 1. If it is a slight mold bounce, we can solve this problem as long as we try to reduce the lubricating oil valve; 2. Stop the crimping machine, take out the dies and clean it up; 3. Adjust the lubricating oil valve to a smaller position; 4. Re-install the dies for trial processing. Generally speaking, the above methods can basically solve the problem of mold bounce. However, these are only expedient measures. We have subjective consciousness to determine the magnitude of the mold bounce of the hose crimping machine. When the mold bounce is severe, we also have to consult the tube shrinking Professionals from machine manufacturers come to answer.

Choosing the right anti-wear hydraulic oil for hose crimping machine

Choosing the right anti-wear hydraulic oil for hose crimping machine The maximum pressure of the hose crimping machine system Z is 31.5Mpa, which is adjusted by the overflow valve. The clockwise adjustment pressure increases, and the counterclockwise adjustment pressure decreases (it has been adjusted at the factory, and can be adjusted by itself if necessary). Mold opening speed adjustment: The speed of mold opening speed is controlled by the diverter valve and adjusted clockwise. The opening speed is increased, and the opening speed is adjusted counterclockwise. The best value is not more than 10Mpa (it has been adjusted before leaving the factory, you can adjust it yourself if necessary). Anti-wear hydraulic pressure is developed on the basis of anti-rust and anti-oxygen hydraulic oil. It has alkaline high zinc, alkaline low zinc, neutral high zinc and ash-free products, all of which are based on 40'C Kinematic viscosity is divided into four grades: 22, 32, 46, and 68. The crimping machine and the pipe pressing machine use No. 46 anti-wear hydraulic oil. Standard of anti-wear hydraulic oil for hose crimping machine: (l). Proper viscosity and good viscosity-temperature performance to ensure that the hydraulic components get good lubrication, cooling and sealing under the conditions of changes in working pressure and working temperature. (2) Good extreme pressure and anti-wear properties to ensure that the friction pairs in the oil pump, hydraulic motor, control valve and oil cylinder are normally lubricated under high pressure, high speed and harsh conditions to reduce wear. (3) Excellent anti-oxidation stability, hydrolysis stability and thermal stability, to resist the influence or action of air, moisture, high temperature, high pressure and other factors, so that it is not easy to deteriorate and prolong its service life. (4) Good anti-foaming performance and air release value to ensure that the foam produced under the condition of mechanically vigorous stirring during operation can disappear quickly; and the air mixed in the oil can be released in a relatively short period of time. Realize accurate, sensitive and smooth static pressure transmission. To put it simply, the function of the oil seal is to seal the oil, and the purpose is to prevent the oil inside the crimping machine and the hose crimping machine from leaking. The oil is a necessary liquid substance in the system, so the oil seal plays a role in the crimping machine and the hose crimping machine to ensure that the oil does not leak. Z is a common type of oil seal, which is divided into monomer type and assembly type. The output and input ends of the crimping machine and the hose crimping machine have oil sealing devices. As the working time is longer, the oil temperature also rises. The oil seal can protect the oil from leaking out, so as to maintain the normal oil consumption. Oil is a liquid substance, it is volatile, and the higher the temperature, the faster it will evaporate. The quality and life of the oil are directly related to the quality of the oil seal. Therefore, a good quality oil seal can increase the working time and life of the crimping machine and the pipe pressing machine. On the other hand, the oil seal also prevents the waste of resources (oil) and cost increase.

Talking about the use of tools in the processing of crimping hoses

Talking about the use of tools in the processing of crimping hoses Efficient In order to improve the production efficiency of the hose crimping machine, more and more clamp products are available for double-sided, four-sided and multi-piece clamping. In order to reduce the installation time of the workpiece, various automatic centering clamping, precision flat-nose pliers, lever clamping, cam clamping, pneumatic and hydraulic clamping, etc., fast clamping functional components are constantly being introduced. Crimping machine manufacturers have discovered through continuous research that increasing the pressure of the tube shrinking machine can not only improve its cutting ability, but it is also very helpful to reduce cutting costs. This was quickly verified. For example, the tube shrinking machine can generate high continuous working pressure through some advanced high-pressure technology. The higher the power emitted by the abrasive material in the water jet, the cutting equipment can cut at a higher speed, and the abrasive material used by it can be reduced accordingly, so the cost will naturally be reduced. In addition to saving abrasive materials, the high compression tube machine technology can also save a lot of time. It is said that time is money, and the time saved can implement more work and create more profits. In addition, compared with ordinary shrinking machine equipment, equipment with higher pressure also has unique advantages in reducing the use of water and electricity. This is also good news for the earth where water resources are gradually scarce. In order to be able to adapt to the high pressure of the tube shrinking machine, we must strengthen the maintenance and maintenance of the air pump and its internal components to meet the ever-increasing stress requirements.
